 not imported hoijs. This points to the eventual substitution 

 of Cotton-seed oil for lard in cooking. 



Bleeding Bread. — Tiiis affection which was epidemic in Eu- 

 rope beven years ago has made its appearance in England. Mi- 

 croscopic spherical cells filled with reddish oil give from a peach 

 blossom to a blood color to the medium in which they grow. 

 In the dark, the deposit extends itself by spurting a sort of jet or 

 column of red particles, so that a large surface is covered with 

 great rnpidity. Treated with sulpho-iodine, it turns blue. 



Bovine Tuberculosis. — The blooded Alderney stock of C" 

 S. Taylor of Burlington, N. J., has been found to be affected by 

 tuberculosis. Out of a herd of 150 cows, some 20 have already 

 been killed and others are doomed, Mr. Taylor being determ-

Hydrophobia. — The Chicago Pasteur Institute in the pre- 

 ventive inoculations against hydrophobia has attained the fol- 

 lowing results since its inauguration, July 2, 1890: 



To date 302 persons have been treated, classified as follows : 

 104 bitten by animals recognized and ascertained to be rabid by 

 the experimental proof made in the laborator}' ; or by the death 

 of other persons or animals bitten by the same animal ; 126 bit- 

 ten by animals recognized to be rabid by the symptoms of the 

 disease shown during life; 72 bitten by animals strongly sus-

 7 by cats, 3 by skunks, 2 by wolves, 1 by a mule. 



The persons treated came mostly from Illinois, Iowa, Indiana, 

 Kansas, Ohio, Missouri and Arizona. 



Only one death was reported among the patients treated, thus 

 giving a mortality of about 0.33 per cent. 



BIOLOGICAL NOTES. 



Red Blood-Corpuscle. — Dr. Moser has concluded that the 

 red blood-corpuscle has a distinct nucleus. He gave methylene 

 blue to a patient internally in one-grain doses three times a day. 

 He then examined the blood and found that nature had done 

 the staining. The nuclei of the white blood-corpuscles were
